ELECTRIC AND COMBINED ELECTRIC AND GAS CHANDELIER OR BRACKET.

I SPECIFICATION forming part of Letters Patent No. 621,104, dated March14, 1899.

Application filed June 6,1898. Serial No. 682,655. (No model.)

To aZZ whom it may concern.-

Be it known that I, WVILLY H. LAU, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented a certain new and useful Electric and CombinedElectric and Gas Chandelier or Bracket, of which the following is aspecification.

My invention relates to improvements in electric and combined electricand gas chandeliers and brackets; and the object of my invention is toobtain an electric and also a combined electric and gas chandelier andbracket in which the ordinary insulatingjoint heretofore used in suchchandeliers and brackets will not be required for the gas-pipe, but inplace thereof a loop (forming a cap and joint to the gas-pipe) or acommon stifi joint will be used to obtain a combined electric and gaschandelier or bracket which can be used without causing combustion fromthe electric conductor or fixture used in connection therewith, and toobtain an electric and a combined electric and gas chandelier andbracket in the use of which no grounding of the electric conductors willbe liable to occur.

A further object of the invention is to obtain an electric and acombined electric and gas chandelier and bracket which will be sightlyin appearance, readily assembled, and durable.

In the drawings accompanying and forming a part hereof the manner inwhich the objects sought is well shown in the mechanisms illustrated, inwhich drawings- Figure 1 is a sectional elevation of a com binedelectric and gas chandelier embodying the invention; Fig. 2, a bottomplan view of the chandelier illustrated in Fig. 1; Fig. 3, a bottom planview of a modification of a portion of the chandelier illustrated inFigs. 1 and 2, showing a chandelier arranged for electric connectionsonly. Fig. 4 is a detail view of the combined gas and electricdistributer, forming an element in the apparatus embodying theinvention. Fig. 5 is a plan View of the combined electric and gasdistributer illustrated in detail in Fig. 4, and Fig. 6 is a sectionalelevation of a stiff-joint cap for an electric chandelier or bracket.

A reference-letter applied to designate a given part is used to indicatesuch part throughout the several figures of the drawings wherever thesame appears.

A is a stiff joint in common use in gas-fittings.

B is an ordinary vertical gas-pipe for a chandelier'secured in stiffjoint A by means of external screw-threads thereon, fittingcorresponding internal screw-threads in stiff joint A.

C is an ordinary gas-distributer.

D is an ordinary casing in common use in gas-pipe fittings.

E is an ordinary canopy.

F is a sleeve on pipe B, of non-electric conducting material, forming aninsulatingsleeve interposed between the casing D and stiff joint A.

G is a pipe of non-electric conducting ma terial forming aninsulating-covering to the gas-pipe B.

H is an electric distributer comprising the central body part it ofnon-electric conduct ing material, and the metal rings 71. h, securedtogether and to the part h by the bolts h 72 having nuts k 71respectively, thereon. Body part h of electric distributer H may becomposed of two pieces h h, as illustrated in Fig. 4. The upper ring Ithas lugs or projections 71 h on the peripheral edge thereof, and thelower ring h has short projections 716 h on the peripheral edge thereof,arranged to engage with projections k W, respectively.

I I are holes through the central body part 71. of non-electricconducting material,through which the ordinary gas-pipes J J extend toconnect with the gas-distributer C in the ordinary way, as by externalscrew-threads on the gas-pipe engaging with corresponding in-' ternalscrew-threads in the hole in the gasdistributer. The gas-pipes J J thusserve to hold the electric distributer H in place surrounding thegas-distributer 0.. When no gas-pipes J J extend through the electricdistributer H, or an insufficient number to hold it in place extendtherethrough, bolts or screws J J, as in Fig. 3, are used to secure suchelectric distributer to the gas-distributer. When the part h of electricdistributer H is made in two parts, as h h, Fig. 4, the hole I isobtained by having the grooves i 2' made in the respective parts k h.

K is a sleeve of non-electric conducting material on gas-pipe J. Thehole I at the end thereof adjacent to the periphery of the electricdistributer H is made of the same diameter as is the sleeve K, and suchsleeve K enters into such hole I to avoid the necessity of closefittings in assembling the several parts of the apparatus.

L is a metal band having holes Z Z Z therein, through which holes thesleeves K K pass, respectively, thereby insulating such band, as well assupporting it in place.

M is the upper half of a globe, which rests on its lower peripheral edgeon hand L.

N N are internally-screw-threaded holes in projections 71,5 7L5,respectively, into which holes the hollow electric arms or brackets O 0respectively fit, and by which such brackets or arms are supported. Armsor brackets O 0 have external screw-threads O O thereon, fittinginternal screw-threads N N.

P P are holes or grooves through electric body part h of electricdistributer H, through which holes the electric conductors Q pass toenter the arms or brackets O 0, respectively. Vhen part it of theelectric distributer H is made of two pieces, as h h, Fig. 4:, the holesor grooves P P are obtained by making the grooves 19 p in such parts h7t.

Toinsert electric conductor Q in place, hole or slot q having beenprovided therefor, such conductor is placed within the casingD at theupper end of such casing and covered by the canopy E and extendeddownward through the casing between it and the insulating tube ormaterial G to underneath the combined electric and gas distributer H C.From thence the conductor Q is put through holes P P into the arms orbrackets O O and to the electric lamps O O in the ordinary way.

R is a bracket, which may be of metal, secured to the electricdistributer H by the bolts 7&2 7L2, and S is a bolt extending throughbracket Rand secured in an adjusted position therein, as by externalscrew-threads S S thereon, fittinginto corresponding internalscrew-threads R R in bracket R.

M is the lower half of a globe surrounding the combined electric and gasdistributerI-I O, and is held in place against band L by bolt S. Accesscan be obtained to electric conductor Q at any time by removing bolt Sand lower half M of the globe.

WVhere an electric chandelier or bracket only is to be secured to andheld in place by a gas-pipe, the gas-pipe can be closed and thechandelier. or bracket suspended from the loop T, forming a combined capand joint. (Illustratedin Fig. 6.) Loop T comprises the internallyscrew-threaded part i, fitting over the gas-pipe in the same manner asstiff joint A is fitted thereover, and secured thereto by the internalscrew-threads therein engaging with external screw-threads on thegas-pipe, the plate t closing the openingin the gas-pipe, andscrew-threaded part to which the pipe U is secured, as to a stiff joint,by external screw-threads u thereon engaging with corresponding internalscrew-threads i 25 and the hollow body part having hole V therein belowplate 2, through which hole the electric conductor is inserted to extendthrough pipe U.

\V is apipe ortube of non-electric conducting material inserted in pipeU to insulate the conductor Q from such pipe.

Y is a plug in gas-distributer C.

The combined electric and gas distributer H O can be secured to thelowerend of the pipe U, Fig. 6, (which may be ordinary gaspipe,) in the samemanner in which such combined electric and gas distributer is secured tothelower end'of pipe B -that is, by having external screw-threadsthereon fitting into corresponding internal screw-threads in a hole insuch combined electric and gas distributer. In such case the electricarms or brackets O 0 may be of the same size as hereinbefore describedand secured in place to the combined electric and gas distributer II C,as described, and the screws J J, Fig. 3, be substituted for the gasbrackets or arms J J, Fig. 2. The conductor Q will then pass entirelythrough the pipe Uand the combined electric and gas distributer H 0,coming out of such combined electric and gas distributer at the bottomthereof,and from thence through holes P P and into the electric bracketsor arms 0 O, as hereinbefore described.

It will be evident that by having a hole on the under side of thecombined electric and gas distributer II C an additional pipe 13 or anadditonal pipe U can be suspended to the combined electric and gasdistributer, and so more than one series of gas and electric arms orbrackets (or electric arms only) obtained. Where pipe U is to besuspended to the combined electric and gas distributer, an additionalstiff joint A and joint T is interposed between the combined electricand gas distributer and such pipe U.

X X are insulating-rings to canopy E.

To assemble the several parts embodying this invention, the pipe B issecured to stiff joint A, insulating tube or pipe G is placed over pipeB, insulating ring or sleeve F is put in place, casing I) is placed overthe pipe B and tube G, insulatingr ing X, canopy E, and insulating-ringX placed over the casing D to be slid up into place after the conductorQ has been inserted through slot or hole (1 and brought down through thecasing D and the upper half of globe M M put in position. The combinedelectric and gas distributer H O (to which the gas arms or brackets J Jelectric arms or brackets O O, and band L may have been previouslyattached) is secured in place at the lower end of the pipe B and theconductor Q electrically connected (through the holes P P and arms orbrackets O O) with the electric lamps. The lower half of the globe M Mis then put in place and secured by the bolt S.

Before putting the lower half of globe M M in place the lower holethrough the combined electric and gas distributer H O is and bracket,thecombination with an ordinary vertical pipe, gas-distributer andgas-bracket arms, of an electric distributer concentric with thegas-distributer and comprising a ring of non-electric conductingmaterial surrounding the gas-distributer, through which ring thegas-bracket arms extend thereby supporting it in place, electricbracket-arms secured in the electric distributer, a band supporting theupper half of the ordinary ornamental shell, such band concentric withthe gas-distributer and having holes therein through which the gas andelectric bracket arms extend, whereby such bandis supported by sucharms, with non-electric conducting material interposed between thegas-arms and the band,-and means for removably attaching the lower halfof the ordinary ornamental shell to the electric distributer;substantially as described.
